Description

Technical Field
The invention relates to the technical field of IP networks, in particular to a message forwarding method, a message forwarding device, a message forwarding storage medium and electronic equipment based on SRv6 networks.
Background
The SR (Segment Routing) protocol is an evolved extension based on the existing network, and provides the network programmability. The SR is a source routing protocol, and supports that at the start point of a path, a forwarding operation instruction is inserted into a message to instruct the forwarding of the message in a network, thereby supporting the network programmability. Currently, the SR supports two data planes of MPLS and IPv6, and the SR based on the IPv6 data plane is called SRv 6.
SRv6, adding an SRH extension in the IPv6 message to replace the conventional label forwarding function under MPLS, and using 128-bit IPv6 address as the network node identifier SID. When transmitting data, SRv6 is put in SRH in the form of Segment List on the head node transmission path and the SIDs of each node are collected, and represents the number of intermediate nodes by SL (Segment Left), thereby modifying SL value to realize the next hop. SRv6 each node is identified by a SID (Segment ID), which is a special IPv6 address. Each SRv6 node maintains a SID list, which is actually part of the routing table. SRH (Source Routing Head) is a bearer of the SID list, i.e. SR header, and is based on IPv6 Routing extension header (protocol number 43), and adds Routing type 4, which is the most important data encapsulation standard in SRv6 system. The source node from which the original message originated uses the routing header to list one or more intermediate nodes so that the packet travels through these nodes on its way to the final destination.
At SRv6, since the source information directing forwarding is in the SRH extension header, the source routing at overlay layer can be conveniently implemented, and the forwarding path is unidirectional at this time. As shown in figure 1, the IP of the End2 device is a private network address B1::1, the End1 device in the network has a public network address, when NAT exists between two SR End nodes, when the A node sends a message to the B node, the SR source device in the figure encapsulates an SR strategy, the SR strategy is forwarded to the End2 device, and the End2 device decapsulates SRv6 the strategy and sends the message to the B node. When in forwarding, the message can not be forwarded because B1 shows that 1 is the private network address.

The specific description is as follows:
1. and adding an NAT-detect (134) type in a Next Header in an SRH message Header for realizing an NAT detection function. An End node in the NAT in direction, that is, an End2 in fig. 1, sends a NAT probe message (Next Header = NAT-detect) at regular time, and sends the NAT probe message to an End node in the NAT out direction, that is, an End1 in fig. 1. The NAT function is used for the conversion of private network address and public network address, when NAT in direction equipment is a private network address and NAT out direction public network address equipment needs to be accessed, the address of the source IP of the message is converted into a public network address; at this time, a public-private network address translation entry is generated in the NAT device, and when the message in the out direction accesses the translated public network address, the destination address is translated into the private network address in the NAT device and is sent out from the in direction.
2. And adding end.N operation to the End node, and processing according to the Next Header type in the SRH.
The principle of end.n operation is: and if the Next Header shows that the NAT-detect type is adopted, acquiring a source IP and a detected SID of the NAT detection message, and constructing data required by end.N operation processing of the SR. Otherwise, the method is a conventional forwarding mode, namely, the IP address encapsulated by the message is obtained according to the SID, the message is encapsulated again, and the routing is searched to send the message.
After NAT detection, when SRv6 command processing is performed after the message reaches the End1 point, the destination IP address of the message is encapsulated by using the message source IP address obtained by detection, and the message can normally reach the End2 node.
Examples

2) And the End1 node receives the SR NAT detection message, and according to the address A2::1, the End1 node learns that the message is NAT processing operation, and the Next Header in the message is 134, and acquires the source IP and the NAT-detect SID of the message, wherein the source IP of the message is the public network address after NAT conversion, and the corresponding relation between the SID and the NAT converted address (C1::1) can be obtained.
3) When the message sent to the node B from the node A needs to support the SRv6 policy, the package of the message is as shown in FIG. 5, wherein the source from the node A to the node SR is the original message, and the source from the node SR to the node End1 is the package of the head SR; when the End1 receives the message, it finds that SID (A2::1) needs to execute end.N operation, obtains address C1::1 after NAT conversion, when packaging SR header, the source address is SID of the End1, the destination address is detected address C1::1, but not B1::1 in SR list, at this time, NAT conversion item exists in NAT equipment, the message can smoothly reach the End2 equipment, and after reaching the End2, the destination address of the message is converted and reduced to private network IP (B1::1) through NAT.
